Three Men in a Boat (1975)

Jerome (Tim Curry), Harris (Michael Palin) and George (Stephen Moore) need to get away from the hubbub of London. Anxious for relaxation, the trio decide to take a cruise down the Thames River. Their plan is to spend two lovely weeks on the water. But, through a series of misadventures, the hapless threesome realize that they're not quite the sailors they thought they were. And their plans for male bonding get capsized entirely when they are lured ashore by three beautiful women.
